Welcome to Laser Pointer Forums! If you are looking for a laser pointer or want to compare different laser pointer companies, you may want to check out the LPF Laser Pointer Company Database. The link will open in a new window for your convenience.

hello guys, i'm new in here and this is my first question i'd like to ask.
i would like to say that i used the search button but found no results for my question. I am sorry in the case i missed it.

so, i am building my first laser and i am documenting all my project detail by detail.
it will be a 300 mW IR laser. now yes i know it's not a good idea to start with an IR laser at such power but my interest is on this one so i will not switch to another wavelength after what i spent already.

now i'd like to know from you that i suppose are experienced and aknoweledged if those goggles are good and will protect me while working with the laser (supposing i am not going to point it at myself even while wearing the goggles & that i will do my best not to get reflexions).
also, is this kind of laser outputting 808nm wave only or will it output something else like 1064nm wave?

If those O-like glasses are anything like their red laser glasses, they wont block very much of it at all. I would suggest you stick to a reputable brand for safety glasses since you can't really afford to cheap out on those with IR. I hear OEM makes some top notch glasses in many different wavelengths.

These here have outstanding specifications at the wavelength you are working with:
